[SOLUTION] Text Munger (#76)

Hello,

some people solved this quiz in one line, but I did it in 120 :
I would like to read advices what could be improved, even if it’s small
things.

There is still a problem with upper- and lowercase during “demungion”.
“Erevy” would become “every”. But that depends on the dictionary.

Thanks for looking through my code in advance!

Greetings
Robert
